I dress every day. At home, I would estimate I'm dressed about 65% of the time not including being just underdressed which I am 100% of the time. Example: Last night I changed from drab to femme at 8 p.m. I only had a wig, lipstick, and earrings on from about 11 p.m. until 1:30 a.m. when I went to bed at which time I swapped the dress for a nightie. I got up at 7:30 a.m., had breakfast, and then bathed about 8 a.m. That's 12 hours. When I got dressed after bathing, I had to leave home and was underdressed with panties, lace bralette with A/B forms, and thigh high nylons. I got home about 10 a.m. and did some outside work in the yard until noon - all the while underdressed. At noon I came in the house and changed out of my drab clothes, put on a shirt dress, my DD forms, and 3 bracelets. About 2 p.m. the DD forms get removed, the bracelets come off, and back on with my drab slacks and golf shirt. I'll get home about 5:30. I will likely not change back into a dress, etc. until about 7:30 after dinner. So, from 8 p.m. last night until 8 p.m. tonight I will be dressed about 15 hours = 62.5% of that 24 hours. If I do change back into a dress at 5:30, that would be 17 hours = 70% of those 24 hours.
As an aside, my wife was gone most of the morning and didn't return home until a few minutes after I donned the shirt dress and my DD forms. When she saw me, I believer her exact words were, "Oh, you've got your little dress on. Why so early?" The "little dress" reference is to this shirt dress that is also referred to as a tunic top. Anyway, my simple response was I had been working hard outside and I just wanted to relax for a while. I am so thankful I have free reign of when I want to cross dress and how often. The only rules are family and friends are not to find out. Another consideration is my wife prefers not to see me with wig and makeup on. While I am cognizant of that, there are times (rare) that she does see me in full makeup and a wig as well as just lipstick and a wig.
I believe the reason why it is so relaxing is because most of us who cross dress likely feel more "at home" in our feminine clothes. I know I simply like the feel of the fabric, the style choices, and the internal feelings of femininity that I experience. I only wish I could cross dress 24/7. I've no desire (that I'm aware of) to transition; but, to be able to "portray" a woman 24/7 would be pure ecstasy.
Is it okay to cross dress every day? You betcha it is unless you have a wife/SO who is adamantly opposed. Then it's time to negotiate when and where you're able to enjoy doing so.
